Note: Snapshot Data resources begin with a Binary File header.

Nicotine::SnapshotHeader
| Offset | Length | Type | Name | Description | Comments |
|---|---|---|---|---|---|
| 0x0 | 0x4 | int | miNumSnapshots | Number of snapshots | |
| 0x4 | 0x4 | int | miNumChannels | Number of channel data entries | |
| 0x8 | 0x8 | int[2] | maiPad | Padding | [0] 1 (mixer state?) [1] 0x12345678 |
The header is followed by two chunks to be read sequentially:
- An array of channel data of a length determined by the number of channel data entries
- An array of snapshot data of a length determined by the number of snapshots multiplied by the number of channel data entries
A single snapshot is comprised of snapshot data for every channel. Each snapshot datum in a snapshot corresponds to a channel.
